A place for files that might change frequently - especially in size, for example e-mail sent to users on the system, or process-ID lock files. /var/log: Contains system log files. /var/mail: The place where all incoming mail is stored. Users (other than root) can access their own mail only. Often, this directory is a symbolic link to /var/spool ...
The Unix file system (UFS) is a family of file systems supported by many Unix and Unix-like operating systems. It is a distant descendant of the original filesystem used by Version 7 Unix . Design
Write Anywhere File Layout (WAFL) by NetApp is a file layout that supports large, high-performance RAID arrays, quick restarts without lengthy consistency checks in the event of a crash or power failure, and growing the filesystems size quickly. Built using log-structured file system concept, [citation needed] snapshots and off-line data ...
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
Lustre is an open-source high-performance distributed parallel file system for Linux, used on many of the largest computers in the world. Parallel Virtual File System (PVFS, PVFS2, OrangeFS). Developed to store virtual system images, with a focus on non-shared writing optimizations. Available for Linux under GPL.
He documented the file system layout as part of the process. [3] The Linux kernel implementation of BFS was written by Tigran Aivazian and it became part of the standard kernel sources on 28 October 1999 (Linux version 2.3.25). [4] The original BFS was written at AT&T Bell Laboratories for the UNIX System V, Version 4.0 porting base in 1986.
